How many degrees is StartFraction 15 Over 16 EndFraction pi radians? 84.375° 93.75° 168.75° 337.5°
Leno4ka [110]

Answer:

x = 168.75°

Step-by-step explanation:

<u>Angle Measurement Units</u>

To convert from different units for angle measurements, we have to recall that:

180 degrees = π radians

If we are given the angle in degrees, multiply by π/180 to convert it to radians.

If the angle is given in radians, multiply by 180/π to convert to degrees.

We are given the angle:

\displaystyle x=\frac{15}{16}\pi

Multiplying by 180/π:

\displaystyle x=\frac{15}{16}\pi\cdot \frac{180}{\pi}

Simplifying:

\displaystyle x=\frac{15*180}{16}

x = 168.75°

Write an equation in point-slope form of the line that passes through the point (5, 1) and has a slope of -3
bogdanovich [222]

Answer:

<h2>         y - 1 = -3(x - 5)</h2>

Step-by-step explanation:

An equation in point-slope form of the line that passes through the point (<em>x₁,y₁</em>) and has a slope of <em>m</em>:

y - y₁ = m(x - x₁)

m = -3

(5, 1)     ⇒       x₁ = 5,  y₁ = 1

Therefore:

y - 1 = -3(x - 5)
